T0 ALL WHOM IT MAY CONCERN:`

Be it known that I, EDWARD C. JAMES, of Baltimore city, in the oo untyofV Baltimore, and State of Maryland, have invented certain new anduseful Improvements in vCommon Road-Locomotives; andI do hereby declarethat the following is a full, clear, and exact description ofthe same,reference being had to the annexed drawings, and to the letters ofreference marked thereon, making part of this specification, in which-Figure 1 is a side elevation.

Figure 2 is a top view.

Figure 3 is a bottom View.

My invention consists in applying to n common road-wagon,A of any usualconstruction, a. car operated by steam-cylinders, or by any othermotive-power for driving wheels, which wheels, instead of being madewith a.

rim or tire, are to have their spokes, running from the hub to theirextremities, suciently strong to prevent break i, ing, and to notdirectly upon the ground, as the hoofs or shoes ot' horses or otherdraught-animals, and thereby to create such similar actionv by closecontact, and produce suilieient friction between the spokes or arms andthe surface ot the road, to, enabie the apparatus to be propelled up anyordinary inclined plane.

The ditiiculties which have heretofore existed in friction-engines orcommon road-locomotives, grow out of the want of suiicient contactbetween the drivers and theroad, which cannot be obtained by a rim ortire,vnor by the cogged wheels which have been heretofore tried, but bytho use of my invention this contact is secured, and will proveefiectual in producing the proper eiect. v

In the drawings, A is the body ofthe wagon; A1, the steam-ear; B, theboiler; `C,ey1inders; C', oog-wheels for endless chain fromeccentric-shaft; D', main driving-wheels; D', main shaft of thedriving-wheels; E, cams and cccentrics of the engine; E', fore wheels ofthe wagon; F, crank-wheels of the engine;- F, guide-wheel; F2,water-tank; G, gear-wheel, operating on H, the rack-wheel, for turningfore wheels and to guide the wagon; a, straps supporting guide-wheelshaft; b, braces supporting piston-rod attached to the boiler; c,connecting-rod or equivalent endless chain; c', inside endless chainfrom e' to ecccntric-shaft; Z the spokes or arms of drivingwheels; ci',the cog-wheels for the chains or crank-wheels ot' drivers fortheconnecting-rod e, if used; e, piston-rods ot' cylinders; f,connecting-rod or pitman; 7L, hinges by which the fore-wagon isconnected to the steam-car, and to allow a free motion between them overirregular surfaces.

The main flrivirpig-wheels D, which are worked by the' endless chain e efrom cogwheels on the eccentric-4 shait, may be connected to the rearwheels, either by anendless chain working over the eogged wheelsd d', orby a regular `connection-bar, c, so as to give a doubleeftect upon theVroad-surface, or, in the event of any irregularities of surface, thusworking together, a sufficient amount of contact can, at all times andou very irregular ground, be obtained to cause the proper propulsion ofthe carriage.

Having thus fully described myinvention, whatIclaim as new, and desireto secure by Letters Patent, is-.-'

The combination of the open wheels with a road-wagon, to be driven bysteam, or other equivalent'motivepower, when operating substantially asrequired.

In testimony whereof, I have signed my nume to this specification iu thepresence ot' two subscribing witnesses.

E. C. JAMES.
